Specification of Letters Patent.

Application filed April 2 root. Serial 'N. 369,644.

To all whom it may concern:

Be it known that I, WALTER W. WINsLOW,

w a citizen of the United States, residing-at lock which, when one knob Laredo, in the county of Webb'and State of Texas, have invented a new and useful Look, of which the following is a specification.

This invention has reference to improvements inlocks, and its object is to provide a isturned, will give an alarm and which may be so arranged that the door may or may not be 0 ened by the-turning of said 'k-nob but which oor may be always opened by the turning of the other knob.

which I for convenience, maybe called the outsideknob, to the bolt-operating mechanism that thelatter may be operated by the outside knob when so desired. An alarm.

mechanism is arranged in constant communi- "cation .Witll'thfi outside knob so that the latalarm, andthis whether a connected or disconnected from'thebolt-opter cannot be turned without sounding an the outside knob be crating mechanism.

The invention will be fully'understood from the following detailed description, taken in connection with the accompan ing drawings forming whioh,.

Figure l is a' face view of a lockconstructed inaccordance with my invention; Fig.2 is a face view, with'parts in section, showing the lock with the face plate removed; Fig. 3 isa cross section through the lock and door to which it is applied, parts being shown in elevation; Fig. 4 is part of this speci 1cation, in

- rin in mechanism-Fi 5 is a detail View of 7 tangular shape -with the ro l-back; and Fig. 6 is a detail .view of the connecting device for coupling the outside knob to the look-bolt-operating mechanism.

Tiepth to form a chamber for that of an ordinary look.

a detail viewshowing the "manner of connecting the outer knob to the certain parts of the working mechanism of the lock, which chamber is inclosed by a cover 2 similar to The-front wall of thecasing is provided with a slot 3 for the assage' of the lockin head'4 of the sliding leek-bolt 5. This 100 -bolt 5 maybe of the usual type with a recess 6 for the reception of thefbit of a key introduced into the inside of the casing through a keyhole 7.

The shank of the 1001 -bolt 5 may pass between fixed studs 8, and pivotally connected to one end-of a link 9,

at its rear end it is the other end of which is pivoted, as indicated at 10, to the casing. der the control of a fiat s ring 11 held by lugs 12cast on the casing, an the tendency of the ro'eot the head 4 of the locke slot 3 to the extreme spring'll is to bolt 5 throug t point of its travel. v

, The link 9 is provided with a curved recess 13 to receive the cylindrical ortion-of a rollback 14 provided with ra ial lugs 15 and seated in the casing 1 in't'he usual manner so This link 9 is unthat when moved by a knobin the manner to be hereinafter described-the link 9 will'be' moved about its pivot- 10 and against the action of'the spring 11 so as to cause the head 4 of the lock-bolt to be moved into the casing. This roll-back is'provided 'With a bore 16 which receives the reduced ortion 17'of the shank 18 of a knob 19, t e said shank 18 being provided with an axial, lon itudinal, cylindrical bore 20. Seated in t e portion 20 of the knob drical portion 21 of a knob spindle 22, which latter extends through the casin 1 and is of su cient length to pass throng a door 23 and receive a knob 24 on the o posite side of said door'from that occupied by the lock casing l'. The door is provided with a suitable. erforatio'n 25 .for the passage of the spind e 22, and perforation has nearthe side occupied by the lock casing l a countersunk portion collar 27 made fast on the knob spindle 22 by a screw 28 or otherwise. 1

It will be seen that when the shank 29 of shank 18 is the cylinf 26 of sufficient size to receivea the knob 24 is in contact with theusu'al wearing plate 30 on the outside of the door I. l I

' The knob 19 will const tute the inner.v knobslot 31 the two knobs 19 and 24- are connected end 21 of the knob spindle 22 enters the knob shank 18 and is there provided w1th' a through, slot, 31 of considerable lengthfor longitudinal adjustment of the' spindle 22k 32 is carried by a spring 34 so shaped as to the knob 19 and hold the pin- 32 so that its inneri'end enters the slot 31 in thefs indle end 21 but this sprin has sufficient e asticity to ermit the wit drawal' of the pin 32 from t e slot 31 so that thepin. may be moved out of coincidence with the radial 'assag'e' through the shank ,18.so that the knob spindle 22- will be disengaged from the The roll-back 14 may be fixed to the re- 'duced portion 17 of the shank, 18 by means bf a set-screw 351whether the reduced portion 17 -on the'bore of the roll-back isfcyhndrical orother'wise shaped since vthe set-screw 35 serves to secure the knob 19 to the -lock.

, of'the'door, by'which' is meant that'knob which may be always manipulated to turn the look without the necessity for a'key or other-means for throwing the bolt, andsince 'the knob 19 is in 'cons'tant' operative-connection "with the roll-back 13-.thes'm1 le turning A vwill retract the head 4 of 'the lock-bolt." When the pin 32 is so set as to engage in the together and the roll-back and lock-bolt maybe operated byeither knob, but when the pin 32 is withdrawn fromthe slot31 the ob 24 will not operate the lock-bolt, and, consequently, the only manner in which the lock bolt may be turned from what may be termed the outside of the door is by means oi a key introduced through the keyhole 7.

Now, in order that the knob 24 may not be manipulated for any purpose without giving Y notice to a person located on the other or inner side of the door, there is secured on the spindle 22 a gear whee'l36 seated ina suitable recess 364 formed on the inner face of the doorfand this gear wheel is in mesh'with a gear pinion 37 mounted on the end of'a shaftv through theflock casing -1 andits co'v'er 2 and there enga ingthe rin ing' 5 on 38 extending ,mechanism' of ja suitable be 39 'mounte the cover 2 of the'lo'ck. This bell may beof any suitable or well 'lmown form vwhich will give audible indication when its interior vmeclia'ni'slnz is rnoved by the gear wheel 36 andrpinio 37;{throu h the shaft 38.- The mechanism no f'part jo showni'n the d'rawings."

i It willbe seenthat the alarm bell'willgive. an audible signal whenever the outer knob 24 '18 and the pin is provided at its outer" end with a manipulating head 33. ThJS pm' partially encircle and grasp the shank 18 ofof the knob 19 in either direction be Which in itself forms 5 d'present invention, is not i a hollow s ank ca is turned so that the turning of this knob will indicate to a person on'the inner side oithe. door that the outer knob hasbeen turned.

access through the oor, should-such an attempt be made.

This b'ell, therefore, operates as an ordinary: 1 door bell with the additional function of givmg notice of a surre titious attempt to gain East to the front or face plate of the lock there is a spring 40 extending across said face plate and beyond the same adjacentto the ead 4 of the lock-bolt.

head 4 'is withdrawn in the lock casing is intelled by the s ring 40 into the path ofs'aid ock-:bolt and t erefor'e holds the same from being again projected by the spring. 11 when The free end'of this spring carries a block 41 which, when the the knob 19 or 24 'is released. pNow, when the door is closed, this block 41 will-be en- 'gaged by the usual keeper 42 on the,door 'casin before the door has quite reached the close position,- and this block 41 will be held" stationa 'as the door continues toward the complete y closed position. The result is that the block 41 is moved out of the path of the head 4 'andwhen the casingl is coincident with the keeperj42 the head 4 is en- 'tirely free and is impelled into-engagement with the keeper 42 by thespring 1'1.

' When the etch-bolt 5 is operatedby either one of the knobs so that its head 4 .is with- I drawn from the keeper 42 the resiliency of the spring .40 will cause the doortto be thrown open, this'spring' being made strong enough for the purpose,- and-when theidooris closed the spring 40 will retard its movement after the b ock 41 engages the'keeper- 42 and will thereforeact to an extent as a spring check for the door;-
